Estella Currin, 40, told her daughter she was heading off to her nursing job around 11 a.m. Sunday. Her husband, Jeff Currin, said the woman he’s loved for 13 years simply disappeared.

“Thirteen years,” Jeff said. “As a matter of fact, she’s my best friend. She’s been with me since my first wife passed away. She helped me with my daughter ever since she was 9 years old. You know, that’s her mother.”

Currin’s keys and wallet with her driver’s license inside were found at a Milwaukee lakefront parking garage and were turned over to art museum security around 2 p.m. Sunday.

Stepdaughter Marquia Currin was the last family member to see her.

“She was rushing,” Marquia said. “She was saying she was late to work and she ran downstairs to get some clothes.”

Currin often took a county bus to her nursing job at St. Camillus in Wauwatosa or her other nursing job near 92nd Street and Capitol Drive.

“I really don’t know and it’s kind of getting to me because, you know, I was the last to see her,” Marquia said.

Jeff said it isn’t like Currin to leave the house and stay away.

“Every time she leaves the house, she always checks in. Always,” Jeff said.

He said one of the most difficult things is their 6-year-old daughter keeps asking where her mother is.

If anyone knows anything about Currin's whereabouts, they are asked to call Milwaukee police at 414-935-7405.
